10.2.3.3 Interpret Diagnostic Data
Use the formulas above to convert raw diagnostic data fields below to usable values. Some fields are scaled by additional
factors.
10.2.3.3.1 top:hv
The HV field comes from the sensor's top board. It represents the high voltage bias to the APD (Avalanche photodiode).
Its operating range is -150.0 V to -132.0 V.
To convert the raw value, use
Equation 10-1 above
then scale the result by subtracting 5.0 and multiplying the result by
101.0.
Example:
hv = 2917
(raw value)
(2917 * 5.0) / 4096 = 3.561
101.0 * (3.561 - 5.0) = -145.34 V
